Tankless water heater maintenance

Welcome to Muller's Plumbing! Today, we're diving into the essential topic of tankless water heater maintenance. A tankless water heater is a fantastic investment, providing endless hot water on demand and energy efficiency. However, like any other home appliance, it requires regular maintenance to ensure optimal performance and longevity. Let's explore how you can keep your tankless water heater in top shape.

Before we delve into maintenance tips, it's crucial to understand how a tankless water heater operates. Unlike traditional water heaters that store hot water in a tank, tankless models heat water directly as it flows through the unit. This on-demand system not only saves space but also reduces energy consumption, as there is no need to keep a large volume of water constantly heated.

1. Descaling Your Tankless Water Heater
   Over time, minerals such as calcium and magnesium can build up in your water heater, especially if you live in an area with hard water. This buildup, known as scaling, can reduce efficiency and potentially damage your unit. Descaling your tankless water heater every 6 to 12 months is essential to prevent this.
   Steps to Descale:
   
   • Turn off the power supply and close the water valves.
   • Connect a pump to the service ports and use a descaling solution (usually vinegar or a commercial descaler).
   • Run the solution through the system for about 45 minutes.
   • Rinse the system thoroughly with clean water to remove any residual descaler.
   • Reconnect everything and turn the power back on.

1. Cleaning the Inlet Filter
   The inlet filter prevents debris from entering your tankless water heater. A clogged filter can restrict water flow and reduce efficiency. Check and clean the inlet filter every few months.
   Steps to Clean the Inlet Filter:
   
   • Turn off the water supply to the heater.
   • Locate the inlet filter (usually near the cold water inlet).
   • Remove and inspect the filter for debris.
   • Rinse the filter under running water until it’s clean.
   • Reinstall the filter and turn the water supply back on.

1. Inspecting and Flushing the Unit
   Regularly inspecting your tankless water heater for any signs of wear or damage is crucial. Look for leaks, corrosion, or unusual noises. Additionally, flushing the unit annually helps remove any sediment buildup.
   Steps to Flush the Unit:
   
   • Turn off the power and close the water valves.
   • Attach a hose to the drain valve and place the other end in a bucket.
   • Open the drain valve and allow the water to flush out any sediment.
   • Close the valve, remove the hose, and reopen the water valves.

1. Checking the Venting System
   Proper ventilation is vital for the safe operation of your tankless water heater. Ensure that the venting system is clear of obstructions and that there are no leaks or damage. Inspect the venting system at least once a year.
   

              Steps to Inspect the Venting System:

• Visually inspect the vent pipes for any blockages or damage.
• Ensure that the vent termination is clear of debris and properly sealed.
• If you notice any issues, contact a professional to repair or replace the venting components.

While regular maintenance can be performed by homeowners, certain tasks are best left to professionals. If you notice any of the following issues, it’s time to call Muller's Plumbing for expert assistance:
